And after experiencing a summer of disappointment in the transfer window last year, the United manager has vowed to make even more key signings this summer.

"I want to bring more Wayne Rooneys to Manchester United," Moyes told MUTV after the club announced Rooney had signed his new contract. "We're having to build again and start again.

"Part of the rebuilding is making sure that you keep the players you really want to keep. We are looking to bring the best players in the world to the club. Wayne Rooney is one of the best in the world.

"I will be looking to make more signings in the summer and hopefully add to the quality we already have got. It tells the fans it'll get better -- and it will.

"I've had great support from the owners and the board -- and it won't be the last, that's for sure.

"I am thrilled that we have got Wayne Rooney to stay. He has been fantastic. Everyone would want him in their team.

"There were clubs who did want him. There were clubs who would have wanted him [had he not signed a new deal] but there was never going to be a chance he was going to leave Manchester United, certainly not on my watch.

"Wayne is a great but he's got a real chance to improve and be a legend. He has matured. It's a bit like deja vu because I remember signing him as a 16-year-old.

"He's an overall team player. Look at the effort he puts in for the team. He needed to reinvent himself [last] summer and I think he did that. He came back and everyone saw the aggressive, tenacious, hungry, goal scoring Wayne Rooney again."
